tst_QComboBox: fix memleaks in task_QTBUG_52027_mapCompleterIndex()

Both the QCompleter and the QSortFilterProxy objects are not owned by
the QComboBox merely by setting them as completer and model. Having no
other QObject parents, and having being allocated on the heap, they
were leaked.

To fix, give them the combo-box as QObject parent.

Amends 8b6d6d4832ea8ed5f9857d5ddf06408ee9d0b4e0.

Pick-to: 6.9 6.8 6.5 5.15
